Removing and installing parking assistance system and parking assistant sensors

Note: Sensors placed on painted surfaces - before installation, the front surface of the new sensor must be painted in the color of the bumper. Parking assistance system sensors may be coated with a layer of paint up to 100 nm thick max. Before painting the sensor, the back of the sensor must be taped (connecting clamps). Only the upper (visible) part of the sensor membrane is painted. To make it easier to remove the "arrow A" clamps, you can use larger pliers with bent jaws.

Turn off the ignition and all electrical consumers.

Parking Assist Sensor Bracket - Drilling, Compatibility, Mounting Position, Bonding Process

When replacing a bumper, new sensor holders must be glued into the new bumper.

Mounting position of sensor brackets

The mounting position is determined by the protrusion on the bracket "2" and the contour of the bracket on the bumper "1".

The process of gluing the sensor brackets

Note: The brackets for the parking aid sensors have a countersunk collar, the front surface "1" of which is painted in the color of the bumper. The brackets for the parking aid sensors do not have a countersunk collar "1". Therefore, to precisely center the bracket in the bumper, it is necessary to use a centering mandrel or glue in the holder with the embedded parking aid sensor, on which the decoupling ring sits (black silicone ring). The temperature of the bumper and sensor holder during gluing should be between 15°C and 30°C.

Clean the marked bonding area "1" and degrease thoroughly with isopropanol (technical alcohol). Apply 3M activator "Plastic Primer 4298UV" or "Primer K520" evenly to the marked gluing area "1". Allow the activator to dry for about 5 minutes.

Note: Observe the installation position and the suitability of the sensor bracket. The contact pressure and holding time are decisive for the quality of the bonding!

Remove the protective film from the double-sided adhesive tape and, pressing firmly, hold the bracket of sensor "2" in the bumper for about 10 sec.
